Result: In diabetes group, the mean age was 53 years and in non-diabetes group, the mean age was 52 years. There is an insignificant association between groups according to abnormal abdominal diameter with p-value>0.05. There is an insignificant association between groups according to MCV, MCH, MCHC, PLR and RDW with p-value>0.05. There is a significant association between groups according to MPV with p-value<0.001. The mean (10.26) is higher in diabetic group than the mean (7.98) of non-diabetic group. On applying regression analysis there is very mild association of MCV with HBA1C. On applying regression analysis, there is no significant association of RDW, PLR, MCHC, and MCH with HbA1c.
